T 0 all whom it may concern:

Be it known that I, WILLIAM SANDFIELD IVILSON, of the village of Ayr, inthe county of \Vaterloo, in the Provinceof Ontario, Canada, machinist,have invented certain new and useful Improvementsin Harvester-Rakes; andI do hereby declare that the following is a full, clear, and exactdescription of the same.

My iuventiOu has for its object a harvesterrake so constructed thatthere will be the least possible frictional resistance compatible withthe weightand the number of parts in motion. v Myinventioncousistsinimprovements hereinafter described, illustrated in the drawings, andparticularly pointed out in the claims.

In the accompanying drawings, Figure l is aperspective view of thatportion of the rakejack to which my improvements relate. Fig. 2 is aperspective view, on an enlarged scale, of my rake-arm, showing theusualnotch for locking the rake-head theretoin the position for raking, andthe tripper-piece secured thereto by a set-screw when it is desired tomake the rake automatic. Fig. 3 is also a perspective view on the samescale; and Fig. 3, an end View of my rake-arm, showing an additionalnotch at nearly a right angle to the ordinary notch, which I adopt whendispensing with the track or ledge for locking the rake-head to therake-arm in the position for reeling. Fig. 4 is a plan view of therake-jack on a still larger scale, showing, first, the ordinary camwhich controls the "arying positions of the rake-armsduringtheirrevolution; second, the crown-wheel with arm-seats (in dotted lines)below the cam; third, the ascending and descending tracks; fourth, themain plate of the rake-jack, upon which is constructed the track orledge for supporting the rake-head while reeling; fifth, thetripping-cam for unlocking the latch from the ordinary notch in rake-armbefore the wing or elbow of the rake-head comes in contact with theabrupt incline in auxiliary pulley or spring in connection with the cam,the tripping-cam aforesaid pressing back the latch and the pulley orspring turning over the rake-head. This view shows the rake-head in itsposition for reeling, the head havingjust been tilted by the incline infront of the track. Fig.5isa view showing my rakehead as locked on therake-arm and in its position for raking. Fig. 6 is a view of theopposite side of the rake-head, showing the construction thereof. Fig. 7is a plan view of the curved spring, which I occasionally use instead ofthe pulley for tilting the rake, so as to leave the sheaf in a properposition on the grain-table. Fig. 8 is a side view of the same.

A represents the can]; B, the crown-wheel; O, the main plate of therake-jack; G, the track or ledge constructed thereon; D, the atljustableblock with tripping-cam D and the pulley D thereon; E, a steel plate forbridging the space between the adjustable block and the track; F, therake-arm; G, the rakehead; H, the trip, which swings inwardly anddownwardly at the will of the operator, and downwardly automatically bythe cam-tripper 0, (shown in Fig. 2,) attached to the rake-arm; J, theascending track; K, the descending track; I, the tripping-cam, connectedwith the abrupt incline O in front of the track 0; (o, the usual notchin the rake-arm for locking the rake-head in. its position for raking;b, the second notch, which I adopt occasionally for locking therake-head in its position for reeling, thereby dispensing with track orledge G, which notch is constructed with a pocket, in which is a slidingdog, (I, which is pushed against the dog in the rake-head by its comingin contact with the upper outside edge of the descending track, and thusreleases the dog from the second notch, Whichallows the head to turnover to its usual position for raking. 0 is a tripping-piece, (shown inFig. 2,) only used when it is desired to use the rake automatically, andwhich, as the rake-arm is carried around, presses down the trip H andalong with it the tripping-cam Iand theincline U", and allows therake-head to pass over it, with the teeth downward for raking off thegavel. e is a wing or elbow, secured to or forming a part of therakehead, which, in its course of a revolution, comes in contact withthe abrupt incline O and turns the head in its position for reeling.

\Vhen I use the second notch, b, for locking the rake in position forreeling the part of the main plate between the letters 8 and t may beremoved, thus dispensing with the track.

Having thus described my invention I claim-- 1. In a harvester-rake, atrack or ledge constructed with an abrupt incline, C and the movableunlocking-cam I, in combination with the rake-arm having alocking-notch, a, a rake head provided with a locking-dog pressedinwardlyby a spring, and an elbow, 0, projecting from the side inadvance of therake-head, so that when the rake is in operation thelocking-dog in the rake-head will be released from the locking-notch inthe rake-arm by the unlocking-cam I, and the projecting elbow 6 comingin contact with the incline C the rake will be turned over from itsraking to its reeling position, as shown and described.

2. In a harvester-rake, a track or ledge, constructed and attached asdescribed, and an unlocking-cam, I, in combination with a trip, H,hinged to the cam 1, and a tripper, c, attached to the rake-arm Iwhereby when the rake is in operation the tripper 0 will press down thetripper H and also the unlockingcam and allow the rake-head to pass inthe locked and raking position, as shownand described.

3. In a harvester-rake, the rake-head pro vided with a slidinglockingdog, a rake-arm provided with the locking-notch a in the lowerpart of the flange thereof, a second notch, Z), in the same flange andabout at right angles to the notch a, a sliding dog, (I, inclosed in apocket in mid-rake arm, located directly below the second notch, and theelbow c, in combination with the unlocking-earn I, the ledge having theincline G and the descending track K, so constructed that its upperouter edge will, when the rake is in operation, press up the dog d,which will push up the locking-dog in the rake-head and release thesame, so that it will turn down into the notch a. and be released by theunlocking-cam I, and the rake, turned by the incline and elbow 0, willbe again secured by the notch a and carried over and clear of the track,so that the latter can be dispensed with without impairing theetfieiency of the machine.

4. The track or ledge of a harvester-rake, constructed with an abruptincline at the front end thereof, in combination with the elbow e on therake-head and the unlocking-cam D and pulley D at the rear end of thetrack, as and for the purposes set forth.

5. A rake-head having a sliding lockingdog, in combination with the rakearm having the notch for locking the said dog to hold the rake-head inits position for raking. asecond notch at about a right angleto thefirst notch for holding the rake-head in a position for rceling, asliding dog carried in a pocket in the second notch, and means formoving said dog for the purpose of releasing the dog in the rake-headfrom the said second notch while used for reeling, as described.

6. A rakearm having the usual notch for holding the rake-head inposition for raking, and a second notch for holding the rake in aposition for reeling, in combination with a track with the abruptincline therein, for the purposes set forth.

7. The rake-arm having the two notches, as described, and the slidingdog (1, in combination with the rake-head having a sliding dog, and thedescending track K, which presses upwardly the said sliding dog (1 andreleases the rake-head dog, as set forth.
